BM5200
5 kV Digital Insulation Tester
Quick start guide
Safety warning must be observed during use:
The circuit under test must be switched off, de-energised, isolated and
n
checked to be safe before insulation test connections are made. Make sure
the circuit is not re-energised whilst the instrument is connected.
Circuit connections must not be touched during test.
n
After completing a test, capacitive circuits must be completely discharged
n
before disconnecting the test leads. Capacitive charges can be lethal.
Tested items should be firmly shorted out with a shorting link, after
n
discharge, until required for use. This is to guard against any stored dielectric
absorption charge subsequently being released thereby raising the voltage
to potentially dangerous levels.
The voltage indicator and automatic discharge features should be regarded
n
as additional safety features and not a substitute for normal safe working
practice.
It is rare, but in certain circumstances, breakdown of the circuit under test
n
may cause the instrument to terminate the test in an uncontrolled manner,
possibly causing a loss of display while the circuit remains energised. In this
event, the unit must be turned off and the circuit discharged manually.
Test leads, including crocodile clips, must be in good order, clean and with
n
no broken or cracked insulation.
The instrument should not be used if any part of it is damaged.
n
Insulation testing in wet weather conditions might be hazardous. It is
n
recommended that this instrument is not used in these circumstances. If
this is unavoidable, the user must take all necessary precautions.
This instrument is not intrinsically safe and must not be used in hazardous
n
atmospheres.
THE INSTRUMENT MUST ONLY BE USED BY SUITABLY
TRAINED AND COMPETENT PERSONS.
